Gath

Damien Gath, 52, has experienced years of daily involuntary shaking and pain caused by the neurological condition, which he said made everyday tasks a struggle.

Mr Gath was first diagnosed with the disease, a condition in which parts of the brain become progressively damaged over many years, 12 years ago.

Mr Gath underwent treatment with new infusion therapy on 10 July.

Before the treatment, Mrs Gath filmed him at home shaking as he tried to make a cup of coffee.

"I almost can't believe that's me in the video," Mr Gath told the BBC.
